aufs3 GIT release
o news - branch aufs3.15 is created - there seems to exist a problem in tmpfs-idr.patch in aufs3-standalone.git. I am still investigating with Nikolay Pertsev and Guan Xin. - aufs will start supporting fallocate(2) systemcall in next release. o pre-announce I have a plan to remove CONFIG_AUFS_SP_IATTR and fs/aufs/f_op_sp.c. fs/aufs/f_op_sp.c is rather tricky, but it is just for maintain the timestamp of FIFO only. Recently I noticed that I will be able to make it unnecessary by customizing i_op-update_time() which was introduced in linux-3.5. o bugfix - handling an error in opening a FIFO - handling an error in opening a FIFO, the internal list These two fixes are less important since the problem happens only if CONFIG_AUFS_SP_IATTR is enabled. - bugfix remap_file_pages(2) This fix is done in aufs3-mmap.patch. The fixed problem is the incorrect path under /proc after you issue remap_file_pages(2) systemcall. J. R.

Re: WARNING at lib/idr.c:527
Nikolay Pertsev: Notice, how shmem_evict_inode outputs only 3 first times. And... You right, I do not see anything from shmem_get_inode()... That is a mystery. Anyway here is a new and consolidated patch. Apply this after all aufs patches you use and tmpfs-idr.patch. In other words, revert all patches I've sent via mail. And post the kernel log until idr_remove called for id=%d which is not allocated msg. Note that no stacktrace will be printed by idr_remove() but several warnings and stacktraces are added by this patch. J. R.

What did I do wrong?
